Describing someone of African descent. A word that Whites can covertly use to refer to Blacks while Blacks are present. People of color usually lack the ability to swim (have you ever seen the shallow end of a public swimming pool) so this is a proper reference.
A family of non-swimmers just moved in next door.
I did not get a wink of sleep last night because those damn non-swimmers were playing that rap music so loud
code word for a person of african-american decent, usually a customer of a restaurant who leaves a less than average tip, or is unusually hard to please
those non-swimmers didn't even leave me a tip!!
